Definitions

  • This invention comes in the shape of a supplementary seat-back especially made to fit the normal seats of any kind of vehicle, be it a car, lorry or bus; it can also be put to any other practical use where a certain amount of rigidity is required as regards the surface of both the seat and the back, and also serves as a side support for the user's body.
  • the aim of this invention is to make the user adopt an ideal position while driving a vehicle, in order to avoid discomfort and possible spinal injury.
  • the cause of lumbago does not only lie in vehicle seats, but in the position of the controls of the vehicle itself, and it is therefore necessary to avoid the elbows being raised too high and to hold the steering wheel with bent elbows.
  • the knees should also be higher than the sacrum and the back should be in a comfortable position, in order to avoid continuous spasms and stressful psychic conditions.
  • the supplementary seat-back constitutes what can be considered as a device for placing on top of the original seat when the vehicle is in use.
  • the supplementary seat-back comprising two rigid pieces with complementary cushioned parts, is fitted in place so that the rigid part corresponding to the seat, and which comes with a posterior elongation, slots into the intersection between the two parts of the original car seat, while the piece comprising the back has a notch on the upper edge for fixing a piece comprising two connected parts, as the main point of support for the spine.
  • both the upper cushioned part of the body corresponding to the seat and the front cushioned part corresponding to the body of the back have a series of depressions or slits for adaptation to the respective parts of the user's body, specifically the slits on the seat for adapting the buttocks and scrotum and the slit on the back for adapting the area corresponding to the spine.
  • the fact that the two parts of the seat-back are jointed, means that they can be placed one on top of the other when not in use in order to form a folded body taking up only a small amount of storage space. This means that it can be comfortably stored away in the boot or any other part of the vehicle.
  • This supplementary seat-back is complemented with an element or device for holding the user's body in place, thereby preventing sideways movements of the latter.
  • This element or device comprises two belts, the extremities of which are fitted with fastening systems; these belts have two cushioned side supports essential to the user, and which, in view of the fact that they slide back and forth along the belts, can therefore be placed in the required position and adapted to the user's body.
  • This element or device has a special feature whereby it can be adjusted in the upwards-downwards direction in relation to the user's body, and can therefore be set at any height.
  • This element or device obviously serves as a safety belt which encircles the side and front part of the user's body, and is fastened behind the back of the said supplementary seat-back.
  • the spine is well supported and comfortably held in place, thereby avoiding pain-causing factors and favouring a position in which the user will avoid all increase in intradiscal pressure through a slight lordosis of the thoraco-lumbar joint.
  • the supplementary seat-back and its side supports hold the torso in place, meaning that the user's body will move much less when driving round bends, and thereby create the subsequent corrective contractions.
  • the rigidity of the seat-back will support the hip and hold it in place with a slight lumbar lordosis, thereby preventing sideways movements, while helping to keep the knees a little higher than the hip, so that the pedals of the vehicle are operated by moving the ankle, with the heel on the ground, and never with movements of the hip.
  • the rigidity of the seat-back means that it partly functions as a real lumbar orthosis reminiscent of the comfort felt by the back when we sit correctly on a classic kitchen chair.
  • FIG. 1 shows a descriptive plan of the seat-back embraced by this invention, including the complementary belts and side supports intended to prevent sideways movements of the user's body.
  • FIG. 2 shows the same seat-back as represented in the previous diagram with the belts and side supports in their position when in use.
  • the seat-back comprises two rigid plates (1) and (2).
  • the former of the two belongs to the body of the seat and the latter to the body of the back, with the peculiarity that seat plate (1) has a slightly narrower elongation (3) for slotting into the space between the vehicle seat and its back.
  • Both the seat plate (1) and the back plate (2) come with their corresponding cushioned parts (4) and (5), which are upholstered and consist of one single piece in each case.
  • the two parts forming the seat plate (1) with its cushioned part (4) and the back plate (2) with its cushioned part (5) are articulated by means of hinges (6) and (7) on either side, so that the wing (6) of the hinge is fitted to the seat plate (1) and the other wing (7) to the back plate (2).
  • Hinges (6) and (7) open completely in order to allow the bodies of the seat and back to adopt the best position when the seat-back is in use, at the same time allowing the two parts of the seat-back to be folded one on top of the other in order to permit storage in the smallest possible space.
  • the cushioned part (4) of the seat plate has two slits or spaces (8) for the buttocks and another slit or space (9) for the scrotum, while the cushioned part (5) of the back plate also has a slit or space (10) thereby permitting greater support for the spinal column.
  • the upper part of the back plate comes with a notch (11) for fixing parts (12) and (13), which are joined to each other in order to serve as the main point of support for the spinal column.
  • the seat-back described herein comes complete with an element or device comprising two belts (14), the extremities of which are equipped with fastening systems (15) and (16), while two cushioned blocks (17) slide back and forth along the belts (14). These cushioned parts (17) are adjusted to the front or side of the user's body, and are fastened behind the plate making up the back part of the seat-back.
  • Fastening systems (15) and (16) can be also be used to adjust the length of the belts (14), which can therefore be adapted to any size or shape of torso.
  • the cushioned parts (17) are adjustable, they can be moved back and forth along the belts (14) and adapted to the user's body, since the purpose of these cushioned parts (17) is to be placed on either side of the user in order to prevent sideways movements.
  • this seat-back can be applied to any kind of vehicle, be it a car, lorry or bus, and naturally to other kinds of seats.
  • the sizes and materials used to make the seat-back can vary.
